Answer:
Volume = mass / density
V = 7200 / 0.68 (ensure units are consistent)
V = 10588 cm^3
=>approx 10600 cm^3
V = 10.6 litres
This is true do to all the other particules around
x(0.5)(320)=(1.2)(48)(325)
160x=18720
x=18720/160
x=117

Answer:
Is pink in base solution, it provides a visual signal that a solution has changed from acid to a base, is colorless in acid solution.
Explanation:
As all the indicator, phenolphtalein has the property that turns pink when the solution that you have reaches a value of a pH of 9 or above. From 0 to 8 in a pH scale, is colorless. This point in which an indicator changes is it called equivalence point.
